TO ALL PERSONS TO WHOM THESE PRESENTS MAY COME:

Be it known that I, ELISHA ROBBINS, oi' the city and county of Worcester, and State of Massachusetts, have invented a new and useful Improvement in Railways; and I do hereby declare the saure to be fully described in the following specication, and represented in the accompanying drawings, of whicl1 Figure I is a. top view of a railway-track provided with my invention.

Figures 2 and 3 are end views of it. Y

In such drawings, A A are the two rails, formed in sections or short rails in' the ordinary manner. They may be theT 0r H-pattern. YI prefer, however, to make each with a section, as represented in the drawings,

but having a superficial area inv cross-section less than they are usually constructed when they are to be sup-l ported at intervals'by chairs. I combine with each rail a continuous metallic support, to extend from tie to tie of the road-bed, and to embrace such rail on either or both the opposite sides or edges oi' its base. The said supports ot' the two parallel rails I sustain on and by a lateral metallic chair to lic on and be spiked or fastened to the upper surface of a tie, and embrace the supports of the two rails, in manner as' represented in the drawings. I also Vemploye metallic brace to rest on the transverse or duplex chair, and extend from one longitudinal rail to the other, and lap on both their base-portions, or to extend between and` lap upon both of their longitudinal metallic base-supports. The ties ofthe road-bed are represented at B B B, dto. The continuous longitudinal supporters are shown at O C, each of which may be grooved lengthwise, as shown at I; in fig. 3, to receive-the base-part of the rail A, or may be made with a single anch, (as shown at c in figs. 2 and 3,) to lap on the base-Harige of the rail; or the base-supporter may be formed in two separate parts, with a, lapping ange to each, such being as shown at d d in fig. 2. The transverse duplex chair, made with two flanges e e, to overlap the rail-braces or longitudinal supports, is represented at D D D, Ste., as placed on the several ties, and fastened to them. The metallic cross-braces fixed on the duplex chairs, and lapping on the bars of the rails, or on theirlongitudinal supporters, are shown at E E, Ste. They are to be fastened down to the chairs byscrews or bolts. Thespikes used to fasten the transverse chairs tothe ties may be employed to lap on the rail-bases, and, in' such case, they may go through the longitudinal baselsupporters. The arrangement of the parts as above described are represented in the-drawings.

The advantage of my invention is, that by means of it the rails of the track are rmly held in place, so that there can be no breaking down of them at the joints, or spreading of them laterally, under the actions of the carriage-wheels on them, Y

I claim, in combination with an iron rail, a metallic chair or supporter, C, to receive it, and extend longi tudinally and continuously under such rail, and from end to end of'it, and upon a series of ties, or their -equivalent, and lap on either o1' both flanges of-the base ofthe rail7 as specified.

I also claim such a chair, as made or divided lengthwise in two parts, with a lip or iiange to each, to grasp and extend over the base of a rail, as specified. A

` I also claim, in combination with two parallel v.rails A A of a railway, the cross or duplex chair D, made with lips to grasp the bases of the-oppositerails, or two longitudinal chairs or supporters C C, applied thereto in manner as speciied.

I also claim the combination of the metallic brace E with the parallel rails A A, and the transverse or duplex chair D, applied to such rails, or to their longitudinal metallic supports or chairs C C, as explained.

ELISHA ROBBINS.
